Heavy wheeled and tracked vehicle training has been conducted on portions of the landscape of Fort Knox, Kentucky for approximately 60 years. Fort Knox is located on the Kentucky Karst Plain and sinkholes are dominant features of this area. Sinkholes and karst terrain present an atypical problem in combination with this unique land use, potentially impacting downstream and local terrestrial environment. A study of the training area sinkhole complex was conducted as a first step toward mitigating the impact of military activities and reduces potential problems of sedimentation and water quality degradation. A total of 20 sinkholes within Training Areas 9 and 10 at the Fort Knox Military Reservation were randomly selected to represent the study area. The objective of this study was to determine the relationship between stand structural characteristics, understory light availability and understory vegetation in sinkhole riparian buffers and concentrated flow paths and with the amount of sediment entering sinkholes in the study area. Vegetation data were collected during the growing months of May and June in 2009. All regressions analyses for vegetative structures have r2 values between 0.000 to 0.308 indicating weak to no correlation among the variables. Light availability and percent herbaceous cover showed moderate and weak relationship in buffers (r = 0.547, p = 0.003) and flow paths (r = 0.164, p = 0.245). Sediment gained in splay areas showed no significant relationship to vegetation structure (r = 0.039 to -0.335). The relationship between sediment gained and mean percent herbaceous cover was not significant in flow paths (r = -0.172, p = 0.2341) or buffers (r = 0.130, p = 0.292). While the results of this study suggest the amount of the sediment depositing in the sinkholes was unrelated to observe variation in sinkhole vegetation, the relationship between overstory vegetation and understory vegetation within sinkholes was more noticeable. On site observations strongly suggest that concentrated flow paths were the primary conduits for sedimentation into splay areas. Therefore, management considerations pertaining to training areas should minimize flow paths leading to sinkholes. Best management practices for Fort Knox training areas should integrate these research findings, in addition to current knowledge of riparian buffers and training areas' management requirements.

xv, 296 p. : ill. (some col.) A print copy of this thesis is available through the UO Libraries under the call number: KNIGHT E78.O6 H44 2001 / This study analyzes the botanical and archaeological material from a Middle Holocene occupation at the Bergen site, located in the Fort Rock Basin, Oregon. It serves to complement and enhance over a decade of research focused on regional settlement patterns in the Northern Great Basin. While previous studies in the region have focused on broadly based settlement patterns, this study shifted the interpretive lens toward an in-depth analysis of a single family dwelling, which was occupied some 6000 years ago. It thus introduces the domain of "household archaeology" into the practice of archaeological research in the Northern Great Basin for the first time. Macrobotanical analysis was conducted on 215 soil samples collected on a 50cm grid from this house. An additional 20 samples were analyzed from a second house structure at the site. These analyses have provided evidence of diet, environment, and social behavior associated with the prehistoric occupants of the house. The abundance of charred bulrush (Scirpus ), goosefoot (Chenopodium ), and waada (Suaeda ) seeds in the deposits indicate that small seeds of wetland-adapted plants were an important dietary resource during the Middle Holocene in the Fort Rock Basin. The patterned distribution of botanical material in 215 soil samples across the floor of the house provide strong evidence of prehistoric human activity areas. The highest concentration of seeds and charcoal in the house was located near the central fire hearth, where cooking and food preparation took place. An east-facing entryway is suggested by the presence of a secondary concentration of seeds and charcoal on the eastern edge of the structure. Analysis also revealed a differential distribution of seed types across the house floor. Higher concentrations of bulrush in the northern area of the floor, away from the hearth, suggest the presence of sleeping mats. Results of this study indicate that plant remains are not evenly distributed through archaeological deposits, therefore care must be taken when sampling for macrobotanical remains. Research at the Bergen site provides the basis for recommendations to assist future archaeologists in determining the best and most cost-effective locations within excavations to take macrobotanical samples. / Committee in charge: Dr. C.

Atteindre le régime de couplage fort entre des nanocavités et des systèmes atomiques est un élément clé dans l'information quantique. Durant ma thèse, j'ai designé et fabriqué des nanocavités à cristal photonique en GaInP pour le couplage fort autour de 800 nm, longueur d'onde typique des atomes du Rubidium (780 nm) et de Césium (852 nm), les plus utilisés dans le domaine, ainsi que de l'Argon (811 nm). L'objectif est de faire interagir ces atomes avec la partie évanescente du mode fondamental de la nanocavité. Pour cela, un facteur de qualité de l'ordre de 8.10^4 et un volume modal inférieur à 0,04 µm^3 est nécessaire.La nanocavité est l'élément clé d'une plateforme nanophotonique. Nos plateformes sont composées d'une nanocavité à cristal photonique résonant autour de 800 nm, d'un réseau-coupleur pour collecter la lumière issue d'une fibre optique et vice versa et de guides d'alimentation pour transporter la lumière du réseau-coupleur à la nanocavité. Plusieurs défis technologiques ont émergé. La nanocavité doit avoir un fort facteur de qualité et un faible volume modal, le réseau-coupleur doit collecter le maximum de lumière issue de la fibre, les guides d'alimentation doivent transporter la lumière sans perte et, enfin, un mécanisme pour coupler la lumière des guides d'alimentation dans la nanocavité devait être trouvé.J'ai simulé, designé, fabriqué et caractérisé les éléments de ma structure. J'ai obtenu des facteurs de qualité supérieurs à 10^7 en théorie, et de l'ordre de 2.10^4 expérimentalement, détenant ainsi le record pour les cavités en GaInP autour de la longueur d'onde de 800 nm pavant la voie à la réalisation des expériences de couplage fort. / Reaching the strong coupling between nanocavities and atomic systems is a key element for Quantum Information. During my PhD, I designed and fabricated photonic crystal nanocavities in Gallium Indium Phosphide (GaInP)for strong coupling around 800,nm, typical wavelength of atoms such as Rubidium (780,nm), Cesium (852 nm), the most used in this domain, and the Argon atoms (811 nm).The aim of my PhD thesis is to provide with a nanophotonic platform dedicated to strong coupling interaction. For this, nanocavities having optical resonances arounf 800 nm, with quality factors larger than 8.10^4 and mode volumes smaller than 0.04µm^3 are necessary.The nanocavity is a key element of nanophotonic plateform. Our platforms are composed of a photonic crystal nanocavityitself, a grating-coupler in order to collect light from a optic fiber and vice versa and feeding waveguides in order to transport the light from the grating-coupler to the cavity. An efficient nanophtonic platfom for a reaslitic implementation should have a nanocavity with a large Q-factor and small mode volume. The grating-coupler must efficiently collect the light from the optical fiber, and the feeding waveguides must transport the light without losses.I simulated, designed,fabricated and caracterized the elements of my structure. I obtained quality factors larger than 10^7 in theory, and about 2.10^4 experimentally, getting the record for the nanocavities in GaInP around the wavelength 800 nm, which make them close to realize experiments of strong coupling.

In a culturally diverse South Africa, the debate concerning whose history to commemorate, is an increasingly controvertial issue. In light of this, a refreshing opportunity for the celebration of a shared memory has been identified in the forgotten Mpumalanga mission station, Botshabelo. It is remembered as a place of harmony between different cultures, the natural and man-made landscape, this once self-sustainable, flourishing settlement that now stands abandoned and in a state of decay (Langhan, 2000:25). This dissertation research focuses on design within sensitive heritage environments at various scales, through acts of layering. At the urban scale, the research investigates the possible mediation between heritage conservation and development for a returning local community. At a more detailed scale, the project focuses on the rediscovery of Botshabelo’s cultural precinct through layering of the old fabric with new ritual. And finally, at the precinct vision’s climax, Fort Merensky (which overlooks the Botshabelo valley) forms the dissertation’s site of design focus. Finally, through the reinterpretation of Fort Merensky as a device for ‘hiding’ and ‘revealing’, a cumulative moment is formed by which a (figurative and physical) vantage point for the unlocking and celebration of Botshabelo’s meaningful landscape is enabled. The project intends to create an architectural device for the safekeeping, showcasing and testing of ideas that mark Botshabelo’s memory, learning from it as a model for the development of South African self-sustainable, creative communities. / In ‘n kultuurryke Suid-Afrika, is die debat rondom wie se erfenis behoort gedenk te word ‘n kontroversiele onderwerp. ‘n Verfrissende geleentheid om ‘n gedeelde herinnering te vier is geïdentifiseer in die vergete Mpumlanga sendingstate, Botshabelo. Onthou as ‘n plek van harmonie tussen verskillende kulture, die natuurlike- en mensgemaakte landskap, word hierdie eens self-volhoubare, bloeiende nedersetting vandag bevind in ‘n verlate en vervalle toestand (Langhan, 2000:25). Die verhandelingnavorsing fokus op die tema van ontwerp binne sensitiewe erfenisomgewings op verskillende skale deur middel van gelaagtheid. Op die stedelike skaal ondersoek die navorsing die moontlike bemiddeling tussen erfenisbewaring en ontwikkeling van ‘n terugkerende plaaslike gemeenskap. Op ‘n meer gedetailleerde skaal, fokus die projek op die herontdekking van Botshabelo se kulturele gebied deur die ou stof met nuwe ritueel te laai. As hierdie gebied se klimakspunt, word Fort Merensky wat oor die Botshabelo-vallei uitkyk, die terrein van ontwerpfokus vir die skripsie. Deur die herinterpretasie van Fort Merensky as ‘n toestel om te ‘versteek’ en ‘onthul’, word ‘n kumulatiewe oomblik geskep waardeur ‘n (figuurlike en letterlike) uitkykpunt vir die ontsluiting en viering van Botshabelo se betekenisvolle landskap moontlik gemaak. Die projek beoog om ‘n argitektoniese toestel te skep vir die bewaring, uitstalling en toetsing van die idees wat Botshabelo se verlede kenmerk en sodoende daaruit te leer as ‘n model vir die ontwikkeling van Suid-Afrikaanse self-volhoubare, kreatiewe gemeenskappe. / Mini Dissertation MArch(Prof)--University of Pretoria, 2018. / Architecture / MArch(Prof) / Unrestricted

Today breastfeeding is a common conversation with the ever-growing holistic movement and the effort to 'go green' as demonstrated by the proliferation of the organic food industry in recent years within the United States. Breastfeeding may reduce poor health outcomes including infant morbidity and mortality. Infant mortality is a priority in Tarrant County within southeast Fort Worth as defined by this project’s client Healthy Moms – Healthy Babies – Healthy Community. The purpose of this research was to identify the contextual factors that influence breastfeeding decisions among the zip codes in southeast Fort Worth in which infant mortality is greatest. In analysis of the data among breastfeeding mothers and stakeholders, support was the greatest contribution to successful breastfeeding.

This study seeks to determine the values of and the procedures for establishing a children's theatre activity in the Fort Worth, Texas, metropolitan area. This study has a twofold purpose. The first is to apply the values of children's theatre to children in the Fort Worth metropolitan area. The second purpose is to develop a feasible plan for organizing a workable theatre for children. Chapter II is a review of related literature and is divided into two parts. A history of the children's theatre movement in the United States was presented to substantiate general observations of the values of children's theatre. The final part of Chapter II presents several outstanding children's theatre groups and a brief synopsis of their organization. This is followed by specific organizational needs and suggestions. The final portion of this study presents a feasible organizational plan for the establishment of a children's theatre in this metropolitan area. The plan is flexible enough that other areas could adapt it to their own needs and desires.

This compilation is an in depth analysis of two elementary schools: CandorElementary School located in Candor, New York and Fort River Elementary School located in Amherst, Massachusetts. These two schools show the similarities and differences between a 'factory model' or double loaded corridor with an open plan school converted into individual classrooms. These schools are analyzed both at the macro (entire school building) and at the micro (individual classroom) level. To optimally design an elementary school, the designer needs to be thoroughly aware of the past and current conditions. This understanding will bridge the gap between the teaching methodologies and the teaching environment.
